Emma wanted to make sure I was hard enough.

"We should make sure you're hard enough," Emma looked up at me with a mischievous smirk as she grasped my thick, meaty erection with one hand and cupped my low hanging balls with the other. My cock was already hard enough to smash granite but who was I to protest?

"Yeah," was all I could mumble when she licked the underside of shaft from my balls to the cock head. We locked eyes when she wrapped her lips around the tip of my cock and twirled her tongue around it. I had not gotten a blowjob since Sam and I started trying to conceive since she wanted all my precious sperm in her womb rather than wasted on her tits or in her mouth. I'm sure it was the same with Bill and Emma so I'm sure she was happy to be sucking off another man's cock for a change. It had been years since we last had sex but it was always memorable -- we loved our own spouses but there was something exciting sharing yourself with someone physically without getting too emotionally attached. We were close friends with benefits to put it in another way.

I watched Emma slowly take more and more of cock into her mouth and down her throat, until her nose almost touched my pubes. My wife couldn't do that without gagging! With a muffled moan of satisfaction, she slowly pulled my cock from her lips until the tip of my cock almost slipped out and then she swallowed it whole again. She repeated this for almost a minute until I had to beg her to stop.

"Sweetie, please stop," I begged.

But she continued to give her amazing deep-throat.

"Emma, please," I groaned. "I don't want to cum in your mouth."

That was all it took to make her stop. She slid my cock from her lips and lick the length of it clean of her saliva. "Yes, you have to cum in my pussy."

"I guess I'm more than hard enough now," I grinned and offered my hand to help her stand up. "Shall we?"

Emma climbed up the mahogany Candaleria poster bed, which was very sturdy for my wife and I (or our partners during our swinging days) to have sex for hours but was also feminine with the linen curtains hanging from its metal canopy. She laid back and spread her long, slender legs apart to reveal her wet, bald snatch. There was no foreplay because we were there for one purpose and I was happy to help. I climbed up on the bed and knelt between her thighs.

"So this is it," she smiled at me.

"Yes," I smiled back at her. "Hopefully we can conceive tonight." Of course, to increase her chances of getting pregnant we would have to have sex every day for five days until she she ovulated.
